These images were provided by Todd Kramer. His father, Richard Kramer, worked on the ISEE-3 project and took these pictures. These photos show the final assembly and testing at NASA GSFC in May 1978 after ISEE-3 was moved there from the Fairchild facility in Germantown, MD. We'll be posting more photos from Todd that show the spacecraft being transported to KSC, prepared for launch, and then launched. All photos are copyright Todd Kramer. Click on image to enlarge.
